As a model for mechanistic comparison with peptidyl transfer within the ribosome, the reaction of aqueous glycinamide with N-formylphenylalanine trifluoroethyl ester (fPhe-TFE) represents an improvement over earlier model reactions involving Tris. The acidity of trifluoroethanol (pKa 12.4) resembles that of

4-(Phenylamino)-5-phenyl-7-(5-deoxy-beta-D-ribofuranosyl)pyrrolo[2,3-d]pyrimidine 1 and related compounds known as "diaryltubercidin" analogues are potent inhibitors of adenosine kinase (AK) and are orally active in animal models of pain such as the rat formalin paw model (GP3269 ED50= 6.4 mg/kg). However, the utility of
The utility of PEGylation for improving therapeutic protein pharmacology would be substantially expanded if the authentic protein drugs could be regenerated in vivo. Diminution of kinetic constants of both enzymes and protein ligands are commonly encountered following permanent bioconjugation with

Upon maturation of the human immunodeficiency virus type 1 (HIV-1) virion, proteolytic cleavage of the Gag precursor protein by the viral protease is followed by morphological changes of the capsid protein p24, which will ultimately transform the virus core from

Homopolymers of N-acryloyl glycinamide were prepared by reversible addition-fragmentation chain transfer polymerization in water. The formed macromolecules exhibit strong polymer-polymer interactions in aqueous milieu and therefore form thermoreversible physical hydrogels in pure water, physiological buffer or cell medium.
